Abstract

The invention discloses a photovoltaic energy storage refrigerator car hybrid refrigeration system and a switching method thereof under different working conditions. The photovoltaic energy storage refrigerator car hybrid refrigeration system comprises a refrigeration system body composed of an electric compressor, a mechanical compressor, an expansion valve, a condenser and an evaporator. The power source of the mechanical compressor is an engine. The power source of the electric compressor is a photovoltaic power supply system. The photovoltaic power supply system comprises a photovoltaic panel, a photovoltaic controller, a super capacitor, an inverter and a storage battery. The photovoltaic controller has an effect of controlling the super capacitor and the storage battery to reasonably charge and discharge, the service life of the storage battery is beneficially prolonged, and the discharging efficiency is improved. According to the photovoltaic energy storage refrigerator car hybrid refrigeration system and the switching method thereof under the different working conditions, the mode of double compressors is adopted, thus, the engine can be used to provide the refrigeration power source during refrigerator car transportation, a solar power generating system can be used to supply power for refrigerating during resting halfway, at night and when a carriage needs to be precooled, the problem that an external power source is needed when a refrigerator car is stopped is solved, and the delivery range is greatly expanded.

Description

technical field [0001] The invention belongs to the field of refrigeration utilization, and in particular relates to a hybrid refrigeration system of a refrigerated vehicle using photovoltaic energy storage and a switching method under different working conditions. Background technique [0002] In recent years, with the rapid development of the economy, the improvement of people's living standards and the change of lifestyle, people's demand for fresh food and quick-frozen food has gradually increased, which has greatly promoted the development of cold chain logistics. Refrigerated trucks are used as cold chain logistics The key link, the demand for it is increasing day by day. In 2010, the National Development and Reform Commission promulgated the "Development Plan for Agricultural Products Cold Chain Logistics". The construction of chain logistics system encourages enterprises to transform and purchase cold chain processing equipment to ensure that storage and transportat...
